This is the ProTek R/C Titanium Turnbuckle Set for use with the Team Associated B5, B5M and B5M Lite, as well as the Yokomo YZ-2. 

These titanium turnbuckles are CNC machined and thread rolled to near-exact tolerances from high-quality 6AL-4V (Grade 5) titanium alloy material and polished to a brilliant finish. Each turnbuckle is marked with thread directions for easy identification, with standard sized threads on each end for the intended model.  

Why Titanium?
Titanium is strong, dense and super lightweight. In fact, Titanium has one of the highest strength-to-density ratios of all the metal compounds, making it the best advantage for dropping weight without sacrificing strength or durability.

6AL-4V Grade 5
6AL-4V, or more commonly known as Grade 5, is a Titanium alloy mixture composed of 6% aluminum and 4% vanadium. It is significantly stronger than pure titanium but more expensive to manufacture. Grade 5 is the most widely used titanium alloy for its excellent combination of low weight, high strength and corrosion resistance.


  • CNC Machined Construction
  • High-Quality 6AL-4V Titanium Alloy
  • Reduces Overall Vehicle Weight
  • High Strength-to-Weight Ratio
  • Uses 4mm Turnbuckle Wrench (not included)


  • (6) 3x50mm Titanium Turnbuckle
Note: To ease the installation of new ball cups, add a small dab of ProTek R/C "Premier White" Grease (PTK-1412) to the threads of the turnbuckle.

Don't waste your money on these. The threads on the Protek turnbuckles I received are very shallow, and 2 of the 6 I put on my YZ-2 either pulled out of the ball cup, or pushed all the way into the cup on mild crashes. Spend a little more and get quality turnbuckles from Lundsford or the OEM.)
